I spoke with SAP’s Chief Sustainability Officer Peter Graf recently about some of SAP’s internal initiatives around reducing their carbon footprint. One of their biggest sources of emissions is company cars (22% of emissions in Q2 2012 – the only higher was business flights at 42%).

So SAP started a program to encourage car sharing called TwoGo. The program has an app which matches people who are driving to work, with those looking for a lift. It matches people based on common interests (and allows you to block people you don’t like!).

It allows you to track who’s the Greenest of your friends and it incentivises people by having allotted parking spots for car-poolers. Another nice incentive was that the money you saved from your carpooling could be donated to a charity of your choice – as Peter put it – “You could car pool for a cause”.

The slogan used within the company to promote carpooling wasn’t about saving the company money, or about saving the planet, it was “Make New Friends – Know the Gossip.” Even the CEO joined in.

At the time of the video above, SAP had created 20,000 car pools. It will be interesting to see how getting the employees engaged in this project will affect the 22% of emissions in Q2 that SAP had from company cars.

Full disclosure – SAP is an occasional client of GreenMonk’s video services.
